Title: Sedimentation centrifuge
Inventor: SUZUKI SOROKU
IPC: B04B1/20
Filed: 1991-08-19
Granted: 1993-04-21
Abstract: A sedimentation centrifuge includes a bowl which is supplied with a feed mixture, i.e., a solid-liquid mixture, from a supply pipe. When the bowl rotates at high speed, heavy solids are displaced radially outwardly toward and sedimented on the inner wall surface of the bowl. The solid particles are then discharged through a discharge hole of the bowl and an outlet passage by a screw conveyor in the bowl. During rotation of the bowl, fins on the screw conveyor assist in separating the liquid into heavy and light liquid phases with increased separation efficiency. The separated heavy and light liquids are separately discharged from the bowl through respective outlet passages.

Title: Electrostatic discharge (ESD) protection for digital/analog mixed mode IC
Inventor: KER MING-DOU
IPC: H01L23/60
Filed: 1997-09-05
Granted: 1999-12-01
Abstract: This invention provides an electrostatic discharge protection assembly to protect the internal circuits and digital-analog interface of mixed mode integrated circuits. In ESD testing scheme, pin-to-pin ESD discharge testing and VDD pin verses VSS pin discharge testing often result in ESD damage, not on the input or output pins of integrated circuits, but in the internal circuits. In mixed mode integrated circuits, to prevent the noise of digital circuit from couplingly interfering with analog circuit via power line, the digital and analog power lines are separated from each other. This type of mixed mode IC having separated power lines is more prone to sustain ESD damage on digital-analog interface. The ESD protection scheme serially connected by diodes provided in this invention can effectively prevent digital-analog interface of mixed mode IC from being damaged by ESD. This ESD protection scheme serially connected by diodes can also be achieved with PMOS or NMOS elements.
